Air track is engaged in designing, installation and maintenance of all types of ventilation systems: both natural and forced systems, ventilation and air extraction. To do this, we have professional designers and experienced installers. In addition, we conduct an audit of climate control systems and carry out repair of the equipment in the event of problems.

ventilation
Ventilation is used for training and the supply of fresh air into the room. When this occurs it cleaned and, if necessary, heating or cooling. For each type of air handling equipment has a special, part of the ventilation system.
Thus, in order to clean outdoor air filter is provided. For thin air purification using two filters - coarse and fine filter - mounted one behind the other. The heating is performed in the air heater (air heater), which can be electric or water. Finally, the cooling air is carried out in air cooler, which can be water or freon.
Exhaust ventilation
Removal of air from the space systems of ventilation. This can be a total draft of a plurality of building spaces (general exchange exhaust ventilation system) ...
... and local or local specialized system (extract from toilets, extract from the process equipment, hoods with grease for plates and other kitchen equipment, etc.) .
Given the need to separate the exhaust system from groups of different rooms and categorizing the fire danger in the object, as a rule, the number of exhaust systems is greater than the supply air. This should be observed overall balance: fresh air volume must be equal to the volume of the exhaust.
Note also that, since the purpose of ventilation - to remove the dirtiest and exhaust air, the hood is prevalent in a "dirty" areas (hallways, bathrooms, kitchens, warehouses, etc.). Of the more "pure" premises hood is produced in a smaller volume than the inflow. This ensures that the movement of air in the facility: from "pure" space in the "dirty". In other words, that no air was coming from toilets to workplaces and from the kitchen to the bedroom.

Natural ventilation
Natural ventilation - ventilation is that carried out by the natural movement of air. Natural ventilation can be both supply air and exhaust.
The simplest example of natural ventilation - ventilation of the room by creating a draft. When you open the windows or doors in the two ends of the room in a natural way due to the pressure difference between the air movements occurs, the so-called draft, which provides fresh air into the room.
No less common and natural exhaust ventilation. Thus, in all homes in the areas of bathrooms and bathrooms have exhaust grilles, leading to vertical exhaust shafts extending from the basement to the roof of the building. Due to the pressure drop in the flats and the mine occurs naturally exhaust air from the apartment.
Thus, the lattice and vertical duct - this is the simplest example of the natural ventilation.

Forced ventilation
Forced ventilation is different from the natural presence of the fan - a device that moves the air is not at the expense of natural forces, but by electricity. This makes it possible to avoid many of the limitations associated with the use of natural ventilation, and make the system comfortable to humans and manageable.
So, forced ventilation allows to deliver or remove air in the rooms, creating the required ventilation, significantly reduce the diameter of the duct, get rid of the overall vertical shafts in favor of the smaller ducts, which can be laid in any direction.
It is important to note the possibility of controlling the forced ventilation. Thus, in the case of natural ventilation exactly set the air flow, its temperature, etc. In mechanical ventilation systems provided for this specific equipment -. Fans to control the overall air flow valve for controlling the supply and exhaust air through one or another grating sensors for regulation temperature and so on. As a result, forced ventilation systems are much more reliable, functional and flexible in operation.
